To all/whom it may concern.'

Be it known that I, JOHN SCHMIDT, Jr., a citizen of4 the United States, residing at Philadelphia., in the county of Philadelphia and State of Pemsylvania, have invented certain new and useful Improvements in Cookers, of which the following is a specication.

My invention relates to the class of cookers especially adapted for use in the cannilrilg art.

he object of my invention is to provide a cooker having a relatively great can-capacity 1n roportlon to its size. This I accomplish y providing a can-path which 'occupies substantially the whole interior area, of the cooker.

My invention consists in the novel cooker which I shall now fully describe, by reference t0 the accompanying. drawings, in

which- Fi'gure 1 is a broken end view of my cooker, partly in elevation and partly in vertical cross section.

Fig. 2 is a broken top plan view of the same.

F ig. 3 is a detail sectional view, enlarged, of the can discharge from the switching chamber.

Fig. 4 is an end elevation showing the driving mechanism.

l isa Vshell inclosin what I -shall term the cooking chamber indicated by A, and the Aswitching cham er indicated by B. Both chambers are substantially cylindrical in .cross section, and have a diameter and length dependent upon the redetermined capacity of the machine. he switching chamber is located opposite the uprising quadrant of the cooking chamber, and communicates' with said cooking chamber by a corridor C, also included in the shell walls, and extendin substantially tangential to the to o-sai cooking chamber.

Wit in the cooking chamber, and supported by longitudinal plates 2 carried by the heads or ends of the shell are the can-rails 3, preferably of angle section. These rails or involute section indicated by 4, and an outwardly leading s iral or involute section 4', the former inro ling and the latter unrolling, and the coils of the two portions being relatively intermediate, that is alternating, as shown in Fig. l. The innermost coil of the inleading involute section 4 reverses itself about the center of curvature and merges into the innermost coil of the outleading involute section 4. A plurality of arallel inleading can-rail paths indicated by 5 lead through the corridor chamber C to the peripheral extremity of each of .the inleadin involutes 4 and a plurality of parallel inc ined outleading can-rail paths 5- lead from each of the peripheral terminal's of the outleading involutes 4, back through said corridor chamber. Figs. 1 and 2. In the switching chamber B, the inclined outleading can-rails 5 respectively join by sections 6 succeeding inleading can rails 5, thus formin a' plurality of angularly directed switc ing can-paths vleading successivel to and from successive can-paths in the coo ing chamber. Thus, if a can be fed to the first inleading pathl 6 in the switching chamber, it will proceed through the first inleading corridor path 5 into the peripheral extremity of the first cross sectional inleading involute ath 4 in the' cooking chamber, and throug the spiral course thereof to the central cross sectional region of said cham-ber. Here it reverses its course and proceeds outwardly through the outleading involute path 4 of said first cross section and through the first inclined outleading corridor path 5 and through the second switching chamber path 6 into the second'inleading corridor ath 5 and by the latter is advanced into t e inleading involute section 4 of the second cross sectional path of the cooking chamber, and out again through the outleading section 4 of said second path and through the second outleading inclined corridor path to the third spiral path in the cooking chamber; and so on throughout the length of the machine, until it is ready to emerge from the last path of the switching chamber. The can has thus been carried successively and repeatedly to and from the cooking cham- .ber axis, through as many cross sectional areas as may be predetermined in @1.9i Origis shown in Fig. 2. The rods extend lengthwise of the chambers A and B and corridor C and moveV through all parallel cross-sections of the paths, being directed byuY suitable guides, and the center reversing sprockets 10 and terminal bight sprocket 11, to follow the designated paths.

The chains are driven from ashaft 12, carrying a ear 13, F ig. 4:, meshing with a vgear 14'on t e shaft 9, of one of the center reversing sprockets 10. In a housing 15 carried above b the switching chamber portion B of the shell 1 is a rotatable can inlet valve 15', Fig. 2, mounted on a shaft 16 and adapted to receive the cans from a chute 17 and to deliver them to the first can path of said switching-chamber. Carried by the ortion B below is a housing 18 in which 1s' a rotatable can-outlet valve 19, Fig. 3, adapted to .receive the cans from the last can path of the switching chamber and deliver them to a discharge chute 20.

21 is a motor, Fig. 4:, carried by lthe shell 1. The motor shaft 22 has a worm 23 meshing with a worm-wheel 24 on a counter shaft24 carrying a pinion 25 which meshes with a large gear 26. The gear 26 meshes above with a gear 27 on the shaft 16 of the inlet valve and below with a gear 28 on the shaft of the outlet valve 19, whereb both valves are rotated. The counter sha t 24: also carries a gear 29 vwhich meshes with a large gear on the shaft 12. The shell 1 may be heated in any suitable manner b a suitable medium. have not deemed 1t necessary to show Aheating' means as these are well known in this connection.
